FIR Airspace will not be generated with "AN Amsterdam FIR" ( empty kml
file)
Same for Brussels FIR. If I comment the with "* AN Amsterdam FIR" it
does generate a kml file

KML FIR airspace cannot be generated with AN is set to FIR ( KML file
without data)
As soon as I comment the line with a * it works but not with "AN
Amsterdam FIR "
Same for Brussels FIR

Thanks for spotting this, Ren�. I've added this bug to our issue list:

https://github.com/BartVandewoestyne/oaconvert/issues/92

I will take a look at it as soon as I have some time... but my time is
quite limited for the upcoming week...

Regards,
Bart

Hmm... I'm starting to see the problem... line 97 in KMLState.cpp looks as follows:

    if ( !( airspace.isFIR() || airspace.isMapEdge() ) )
      // generate KML polygon and stuff

so we don't generate a 'polygon box' for a FIR...  I must have done this intentionally... probably because the FIR zone is over all other zones and then the rest is hard to see... The question is if we want this behavior or not.  One could argue that FIR's *do* need to be generated, because one can always switch their visualization off in Google Earth...

What do you guys think?  Should we visualize FIR's in the KML output?  If 'yes', how?  Only with a polyline?  With a 'polygon box' because FIR's also have lower and upper limits?  The discussion is open! :-)

Bart

Being a newbe here I do hesitate to comment but: since a FIR is an
infinite space ( GND/SEA uptill GOD in heaven) we should not bother
to fill it.
With my paramotor I hope I will never go below GND and for GOD, well I
hope this will take still some years.
Seriously I mean a line is enough.

regards
René

Not totally correct: if you look in the Belgian eAIP, then you'll notice
that Brussels FIR is defined from GND up until FL 195. See

http://www.belgocontrol.be/website/eaip/eAIP_Main/html/eAIP/EB-ENR-2.1-en-GB.html#ENR-2.1

But I totally agree that a polyline visualization could indeed be more
than enough.

Mmmm
I wonder who gives service above FL195 in Belgium. ;-) "Any portion of
the atmosphere belongs to some specific FIR" see

Above FL195, according to the info in the AIP online at

http://www.belgocontrol.be/website/eaip/eAIP_Main/html/eAIP/EB-ENR-2.1-en-GB.html#ENR-2.1

we have 'Brussels UIR' which stands for 'Brussels Upper Flight
Information Region' and it seems like Maastricht UAC and Brussels ACC
are in control there (depending on the Flight Level).

So... to be complete, we could also add these airspaces to our OpenAir
files... but of course they won't be relevant for paragliding and
paramotoring. But since Google Earth has the capability of turning off
individual polygons/zones, the inclusion of these zones doesn't seem
like a real problem to me... users can easily turn them off in the KML file.

Bart
